Special Issue Information

Dear Colleagues,

Ion sensors continue to underpin the research aiming to address the complex challenges we face in many aspects of our daily lives. From personalized medicine to precision agriculture, safety and security, ion sensors play an important role in the development of diagnostics, treatment and the sustainable management of resources.

In the development of ion sensors that can address these challenges, we rely on the development of new analytical methodologies and the application of new materials, as well as the ability to capitalize on innovations in information technologies in order to develop smart, portable devices that can collect data with a significant improvement in spatio-temporal measurement frequency and share the data almost instantaneously.

We would like to invite you to share your innovations that are related to the aforementioned aspects of ion sensors. We would like to read papers on topics such as, but not limited to: electrochemical and optical sensors; methodologies for the application of sensors to in situ analysis; and the integration of ion sensors with electronic devices in, for example, wireless sensor networks or other smart sensor configurations. Moreover, we would welcome papers describing the utilization of statistical processing that enables simpler data processing, resulting in, for example, the better visualization of sensor data.

Manuscript Submission Information

Manuscripts should be submitted online at by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The measurement of electrical conductivity (EC) has long been a tool for understanding soil properties. Previous studies concluded that EC measurement is not an ion-selective method, but these papers did not address the measurement frequency. An experimental tool and method were developed for semi-factory conditions in a large-scale soil trough at the Institute of Technology of the Hungarian University of Agricultural and Life Sciences. A specially designed and built test apparatus mounted on the tractor’s three-point hitch was used as a measuring device. The wear-resistant steel elements of the measuring device were also the sensors for measuring EC. This paper describes the conditions of the measurement series, the measurement results, and our conclusions from the experiments with the soil sensor. Different characteristics were measured in soil moistened with K and Ca solutions at different concentrations. The EC values show an increasing tendency with increasing salt concentration, and we also found that the rate of change of EC is different for different solution ratios. Based on our measurements, we found that the best method to isolate concentration differences is to use the test frequency range 20 Hz–250 kHz. Full article
